. To all whom it may concern:

Be it known that I, ADAM E. Morm, a United States, residing at Alhambra,in the county of Los- Angeles, have invented a new y invention relatesto automobiles which are equipped with internal combustion engines andthe principal object of the invention is to by which the internalcombustion engine of the automobile by a pedal.

A further object'- of the invention is to provide in such a starter anew method of engaging and disengaging from the engine Further objectsand advantages will be made evident hereinafter. Referring to thedrawings which are for purposes only: Figure 1 is a front view of aportion of an automobile with the invention shown in place. Fig. 2 is aside view of the same. Fig. 3 isa front view of the invention with thecover removed. Fig. 4 is a partial view of the invention' with thepulley cover removed. Fig. 5 is a section on the plane w w of Fig. 3.Fig. 6 is a section on the plane p m w of Fig. 5, with the mechanism atl the end of the positive stroke. Fig. 7 is a perspective view of thekick o'utdog. In the automobile art it is common pracinternal combustionengine which must be started by means independent of the-engine. Theordinary method of mechanically starting such an engine is to provide acrank projecting from the front of the automobile between the forwardwheels which is manu- 1 ally operated when it is desired to start up.This necessitates the driver of the automobile getting out of themachine which is inconvenient and which causes some de-.

lay in case the engine stops for any reason. It also necessitates thedriver losing control of the machine in case-it is started orin case itis necessary to move it quickly to avoid impending dangers.

provide a mechanical starter an extension27 formed on a cover 28 whichtice to drive the automobile by means of an Patented Mar. 7, 1916.

Application filed November 9, 1914, Serial No. 870,965.

In my invention I provide a pedal 10 which is pivoted on a pin 11secured to a bracket 12 which is secured to the frame 13 of anautomobile, the pedal 10 having a pin 14 at its lower end to which isattached a pull rod 15. A flexible tape 16 is secured to the end of thepull rod and passes over a pulley 17 carried in a bracket 18 which issecured at19 to the frame 13 of the automobile. The flexible tape 16passes through an opening 20 in. a housing 21 which is secured by meansof lugs 22 and bolts 23 to the forward end of the automobile in such aposition that a starting shaft 24 which passes centrally through thehousing can be secured to the engine shaft, not shown, of theautomobile, the starting. shaft 24 passing through a bearing 25 on theautomobile. A cap 26 is threaded into is secured by means of bolts 29 mg21, and the shaft 24 has cured therein. and projecting to the housa pin30 sefrom either side thereof.

When it is desired to start the machine by hand, in the ordinary method,the cap 26 may be removed and a crank inserted 1n the projection 27engaging the pins 30 so that the shaft 24 must be rotated in theordinary manner by this auxiliary crank which is ordinarily removed andcarried in the machine, being only utilized in case of accident to thestarter proper.

Rigidly secured by means'of a key 31 to the shaft 24 is a ratchet wheel32 which is provided with saw shaped teeth 33 on the periphery thereof.Loosely mounted. on the shaft 24 is a pulley 34 having a cover 35secured thereto by means of screws 36. Rigidly secured inside thehousing 21 by-means of screws 37 is a spring block 38 in which issecured one end of a spring 39, this spring being coiled around aprojection 40 formed on the cover 35 and having its other end secured ina hole 41 in the cover. The spring 39 is so wound that it tends torotate the pulley 34 in a counter clockwise or negative direction withthe parts regarded in the position illustrated in Figs. 3, 4, and 5,this negative directionbeingshown by an arrow 4, at the beginning rim ofthe pulley in Fig.6. Secured between projections on the pulley 34 andthe cover 35 is a bolt 43 upon which is pivoted a pawl 44 which extendsthrough an opening 45 formed in the 34 in such a manner that it mayengage the teeth 33 of the ratchet wheel 32. The tape 16 is also securedto the bolt 43 in such a manner that it tends to rotate the pulley 34 intheclockwise direction as shown by the arrow 42 in Fig. 3. A kick outpin 46 is also Sivoted in the pulley 34 and the cover 35, an has rigidlysecured thereon akick out dog 47 and a kick out lever 48, the parts 46,47, and 48 turning freely as a unit in the pulley 34 in the cover 35. Apair of stops 49 are formed on the cover 35 and the lever 48 projectstherewith and is stopped thereb A projection 50 is formed inside thehousing 21 in such a mannor that the othenend of the lever 48 strikesthereon thereby arresting the rotation of the pulley 34 at the end ofits negative stroke.

The method of operation of the invention is as follows: The parts beingin the position shown in Fig. 3 the spring 39 holds the end of the lever48 against the stop 50 and pulls upon the tape 16 which is wound up onthe pulley 34. A stop 51 is formed on the pedal 10 and small holes 52are formed on'the pull rod 15 so that the pin 14 maybe adjusted thereinin such a manner that the stop 51 strikes on the frame 13 of theautomobile when the parts of the starter proper are in the positon shownin Fig. 3, the pedal 10 being'drawn into this position by means of thetape 16 and the pull rod 15. With the parts in the pos'tion shown inFigs. 3 and of the positive stroke engages the underside of the pawl 44forcing it into the position shown in Fig. 4 out of engagement with theteeth 33. When the operator wishes to start the machine he presses onthe pedal 1O in the direction of the arrow shown in Fig. 2 therebypulling on the rod 15 and the tape 16. This tends to rotate the pulley34 in the direction of the arrow 42 to produce the positive stroke ofthe starter. As the pulley 34 rotates, the end of the lever 48 is drawnaway fromthe projection 50 so that the the kick out dog 47 presure ofthe kick out dog 47 is-relieved from the pawl 44. In the position shownin Fig. 4 at the start of the positive stroke the tape 16 rests upon thetop of the pawl 44 and tends to force it downwardly into engagement withthe teeth 33. As soon as the pulley 34 has rotated sufiiciently torelieve the pressure on the lever 48 thereby relieving the presure ofthe kick out dog 47 on the underside of the pawl 44, the pawl 44 isforced into engagement with the teeth 33 and the ratchet wheel 32 ispositively driven as the pulley 34 is further rotated by a continuedmovement of the tape 16 caused by a automobile,

continued. pressure on the pedal 10. By means of the sharp kick on thepedal the positive stroke of the pulley 34 is accomplished the enginebeing rotated in the positive or clockwise direction as indicated by thearrow 42 of Fig. 3. This positive rotation of the engine will ordinarilystart it if there is a charge under suficient compression in thecylinders. If not, it may be necessary to operate the pedal 10 one ormore times to obtain the necessary conditions for starting the engine.Immediately upon the occurrence of adequate explosions in the enginecylinders the engine starts to rotate, the shaft 24 continuing to rotatewith the engine. The shape of the teeth 33 is such that the pawl 44slides over them as they rotate. Immediately upon releasing the pressureupon the pedal 10 the spring 39 rotates the pulley 34 in a counterclockwise direction, as indicated by the arrow of Fig. 6, thus causingthe negative stroke of the starter. When the pulley 34 has sufficientlyrotated to cause the end of the lever 48 to strike against theprojections 50 the kick out dog 47 is also rotated lifting the pawl 44positively so that the ratchet wheel 32 rotates freely inside the pulley34. It will be seen that whenever the automobile engine is stopped forany reason it can be started by the driver forcing the lever 10 in thedirection of the arrow shown in Fig. 2.
